Elecromagnetic waves can travel through a vacuum, but a mechanical wave cannot.
Mechanical waves can only exist in a medium, such as air or water. Electromagnetic
waves behave like waves and particles, but mechanical waves only behave
like waves. </span>
Here is the correct question
A constant electric field E = 100 N/C pointing along the positive x-axis is present throughout a region of space that includes the plane bounded by the y and z axes and the lines y = 50 cm and z = 50 cm. The electric flux through the plane's surface, in N ⋅ m 2/C, is
Answer:
25 Nm²/C
Explanation:
given that
The constant electrical field E = 100 N/C
the field lines y and z = 50 cm and 50 cm respectively
= 0.5 m and 0.5 m
For constant electric field, the flux = electric field x area through which field lines are passing
i.e Flux = (100 ×0.5 × 0.5) Nm²/C
= 25 Nm²/C
Therefore; The electric flux through the plane's surface, in Nm²/C is = 25 Nm²/C
The appropriate response is Emotion-centered coping. It is a particular system that was produced in the 1980s by the clinicians Susan Folkman and Richard Lazarus, and these methods concentrate on changing one's passionate response to an unpleasant or disquieting circumstance, for example, getting a finding of a terminal disease.
The statement ‘An advantage of
electron microscopes compared to light microscopes is that electron microscopes
are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes
do not have higher resolution that allows you to view smaller specimens allow
you to view the true colors of the specimens being viewed’ is true. In fact,
electron microscope is more efficient than a light microscope due to its
mechanism using only light without magnifying the specimen a thousand times.
